Maintenance Features

Maintenance Schedule: A detailed schedule outlines routine tasks based on operating hours (After First 5 Hours, After 8 Hours or Daily, Annually (25 hr Use), Annually (100 hr Use)).
Oil Change: Recommended after the first 5 hours, then annually (or more often in dirty conditions). Involves draining old oil and adding SAE 10W-30 4-Cycle engine oil. An oil viscosity chart is provided for different outdoor temperatures.
Oil Level Check: Daily or after every 8 hours of use, using the dipstick.
Air Filter Maintenance: Check and clean annually (or more often in dirty/dusty conditions). Involves removing dirt by tapping or blowing out; replacement is recommended annually.
Spark Plug Maintenance: Service annually (100 hr Use). Involves cleaning carbon deposits, checking and adjusting the electrode gap (0.762 - 0.80 mm), and replacing with an equivalent part (e.g., NGK BP6ES, Champion N9YC) if worn.
Fuel System Maintenance:
- Fuel Valve Service: Annually (100 hr Use).
- Fuel Filter Replacement: As needed if clogged. Requires emptying the fuel tank.
- Draining Fuel Tank and Carburetor: Recommended for long-term storage to prevent gum deposits.
Muffler and Spark Arrestor: Check and clean annually (25 hr Use). The spark arrestor should be inspected for breaks or holes and cleaned of carbon deposits.
Cooling System: Clean annually (100 hr Use). Servicing by an authorized dealer is recommended.
Carburetor Adjustment: Non-adjustable idle mixture valve; adjustments should be performed by an authorized dealer.
Battery Maintenance: Regular charging for the electric starter. Disconnecting the negative cable for storage. If stored for over six months, the battery may need removal and charging.
Cleaning: Remove debris from the generator, muffler, and controls after each use. Inspect air cooling slots for obstructions.
Storage: Recommendations include cleaning, inspecting cooling slots, disconnecting the battery, running the generator every 7 days for short-term storage, adding fuel stabilizer for long-term storage, and storing indoors with a protective cover.
